Description

[0001] The present invention relates to an ice discharge guide for an ice maker,

The present invention relates to an ice making machine for ice making, and more particularly, to an ice making machine for ice making, in which, when ice is formed by spraying water to an ice making part, water sprayed to the ice making part is prevented from flowing out to the outside of the water storage, To an ice discharge guide of an ice maker provided with a water leakage preventing structure for preventing defective manufacture of ice due to a shortage.

As the dietary life and living standards are improved, the number of foods that require ice is increasing, and most of the businesses that sell food and beverages often use ice, so various types of ice makers that make only ice are widely used .

The ice maker generally comprises a refrigeration cycle for producing ice and an evaporator of the refrigeration cycle to form an ice making chamber, and a predetermined amount of water is stored in the ice making chamber, and the stored water is injected into the ice making chamber through the nozzle Thereby forming ice, and guiding ice through the ice making frame to obtain ice having a certain shape.

As a conventional art relating to the ice maker described above, Korean Utility Model Registration No. 20-0416645 discloses a structure of an ice guide device for ice making ice of an ice maker, which comprises a compressor, a condenser, An ice storage chamber 20 for storing ice as shown in FIG. 1 and an ice-making frame 31 which is configured to be in close contact with the evaporator 15 of the refrigeration cycle at the upper side of the ice storage chamber 20, An ice making plate 100 for discharging ice, a plurality of spray nozzles 38 for spraying water to the ice-making frame 31, and a water storage tank 37 for storing water necessary for ice-making, The ice maker 30 constitutes the ice maker 30. The icemaker 30 is supplied with ice water required for ice making and stored in the ice maker 37. The ice maker 30 operates the pump 40 to pressurize the hot water into a plurality of nozzles 38, 38) from ice And the ice making water is sprayed to the inside of the ice-making frame 31 through the discharge guide 100 to form ice.

The water sprayed from the injection nozzle 38 and supplied to the ice-making frame 31 is repeatedly returned to the water-storage tank through the ice guide plate. Ice is frozen in the ice-making frame 31 by the freezing cycle, The operation of the pump 40 is stopped and at the same time, hot hot gas having a compression heat is compressed in the compressor by the evaporator 15, and the ice-making frame 31 is heated to melt the ice cubes in the ice- And the ice cubes scraped from the ice-making frame 31 are stored in the ice storage chamber 20 through the discharge door 36 on the ice discharge guide 100, and the stored ice can be taken out and used. Reference numeral 33 in Fig. 1 denotes a supporting plate for supporting the ice making frame.

As shown in FIGS. 1 and 2, the spray nozzle 38 of the prior art is provided with a horizontal incision opening (not shown) which is linearly cut at a narrow interval so that water sprayed from the nozzle spreads at a predetermined angle and is injected, Shaped cutout 38 formed by connecting the vertical cutout 38a and the vertical cutout 38b are formed at the upper side of the incision as shown in FIG. So that the side of the horizontal incision opening 37a is totally or partially clogged.

As shown in FIG. 4, when the horizontal cut-off port 38a is blocked by the straight cut-out port 38, the water stream which is ejected from the pump due to a predetermined pressure is spread toward the ice- The water stem is injected in the left-right direction of the ice-making frame 31 through the two vertical incisions 38a. Particularly, the water stem injected to the left side of the vertical incision 38a is discharged through the exhaust door There is a problem that the water is discharged from the water storage tank 37 to the ice storage chamber 20 while passing through the opening 36 of the water storage tank 37.

Thus, when the upper part of the spray nozzle is clogged by foreign matter, the water is not normally supplied to the ice-making frame, and in particular, the water circulated to the ice-making frame 31 flows out to the outside of the water- As a result, the ice formed in the ice-making mold, as shown in FIG. 5, is in a normal form, which is equal to the volume of the ice-making mold, due to the lack of water circulating and supplied to the ice- There is a problem that the produced ice is not used and the produced ice becomes unusable and the iced water having a temperature higher than the ice temperature is introduced into the ice storage chamber 20 to cause the stored ice to be thawed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a water jetting apparatus and a water jetting apparatus which can prevent water from being supplied to a water jetting nozzle, In addition, when the upper part of the water injection nozzle is blocked by accumulation of foreign matter, water in the water storage tank higher than the temperature of the ice is prevented from being discharged into the ice storage chamber to prevent the ice from being frozen. And an ice maker.

The jetting part 38d spreads the water to a predetermined width, The ice discharge guide 100 separates a plurality of guide lances 100a at a predetermined interval to form a horizontal incision opening 38a and a vertical incision opening 38b, The injection nozzle (38) A through hole 100b through which water to be sprayed is formed and is connected to an upper fixing table 100c for fixing a plurality of guide teeth and a lower fixing table 100d for fixing the other, The plurality of guide lugs 100a are arranged between the upper fixing plate and the lower fixing plate in a horizontal direction orthogonal to the longitudinal direction of the guide flesh, and water sprayed from the injection nozzle 38 blocks the water discharged toward the discharge door And a plate (100e) is formed to provide an ice discharge guide (100) having a water leakage preventing structure of an ice maker.

The blocking plate 100e is formed in the shape of a plate having a predetermined width so that when the horizontal cutout 38a of the straight cutout 38a of the injection nozzle 38 is clogged by the foreign substance, So that the water stream in the range of the water streams A to B to be sprayed can be prevented from being sprayed toward the discharge door 36.

It is possible to prevent the water that is supplied from the icemaker to the outside of the water storage tank even if foreign substances are accumulated and clogged in the upper part of the water injection nozzle of the icemaker, So that water shortage phenomenon of the water storage tank is prevented from occurring, thereby increasing the ice making efficiency.

In addition, by providing the ice discharge guide with the water leakage prevention structure of the ice making machine according to the present invention, even if the upper part of the water injection nozzle accumulates and clogs foreign matter, water in the water storage tank higher than the ice temperature is prevented from flowing into the ice storage chamber Thereby preventing thawing of the stored ice, thereby improving the ice storage performance of the ice maker.
